THOMAS A. DELANEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO HILLS- MOCANNA- COMPANY, OF CHICAGO, ILLINOIS.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 749,477, dated January 12, 19041 Application filed April 24, 1902.

To all whom it may concern:

Be it known that I, THOMAS A. DELANEY, of Chicago, Illinois, have invented certain new and useful Improvements in Lubricators, whereof thefollowing is a specification.

This invention relates more particularly to the class of lubricators in which the lubricant is drawn from -a reservoir and forced to the point of application by a pump.

In feeding materials of non-homogeneous compositionas, for example, soapsuds, oils containing sediment, graphite lubricants, &c. it has been found that the heavier matters have a tendency to separate from the body of the material and not only not be fed properly, but clog or affect the valves of the lubricator, so that it failed to work right. My present invention is intended to obviate these objections. v

. To this end it consists in certain devices or combinations which are pointed out inv the claims at the end hereof.

In the drawings, Figure 1 is a front elevation of a lubricator containing my invention with a portion of the front wall of the reservoir broken away to show the interior thereof. Fig. 2 is a plan view of the same with the top of the reservoir partly broken away to show the interior. r

In the figures, 1 is the reservoir. 2 is apump mounted on the reservoir and provided with moving on the guide-studs 6 and reciprocated The pump-rod 8 passes through an ear 9 on the nuts 10, so that the pump is operated by the reciprocation of the cross;head.- All these parts are fully described in the patent granted to McCanna and myself October 2, 1900, No. 659,166.

11 represents rods, screw-threaded on.their upper ends, as shown, and passing through ears 12 on the cross-head 5 and connected therewith by nuts 13 on each side of the ears. These rods extend downward through stuffing-boxes 14 into the reservoir. At the lower ends--of these rods, and preferably near the bottom of the reservoir, is a plate 15, suitably attached to the rods, so as to reciprocate with them when they are mowed by the cross-head.

This plate isperforated is shown at 16, to perfierial No. 104,474. (No model.)

mit the passage of the pump-suction, and it is enough smaller than thereservoir to' move easily therein and churn the contents as it moves and keep them stirred up.

While my invention, as above set forth, is intended more particularly for lubricating purposes, it is sometimes available for other and analogous uses. For example, I have used it for feeding boiler compound to boilers and v have had great success with it for that use.

I claim' i 1. In combination with the reservoir, a suction-pipe extending into the reservoir, a pump for drawing through the pipes; and a reciproeating stirrer within the reservoir and con nected with amoving member of the pump to be reciprocated therefrom, substantially as described.

2. The combination with the reservoir, of a pump drawing from the reservoir and having a cross-head through which the pump is rendred active, and a stirrer located in the reservoir and connected with the cross-head to be actuated therefrom, substantiallyas described.

3. The combination with the reservoir, of a pump having its suction extending from the top toward the bottom of the reservoir and its discharge above the suction, of a stirrer in the reservoir and connected with a moving member of the pump to be actuated therefrom, sub stantially as described.

4. In combination with the reservoir, and the pump mounted thereon, and the cross-head by which the pump'is operated, rods "extending from the cross-head into the reservoir, and a plate connected to said rods and fitting loosely in the reservoir, whereby the contents igf the reservoir are churned or stirred up when the pump is in operation, substantially as and for the purpose set forth.

5. In combination with the reservoir,- the pump and the cross-head by which the pump is operated, rods adjustably connected to said cross-head, and extending into the reservoir
